The Blue Donut Carb Cap is a fun accessory that will brighten up your dab sessions. The American handcrafted Blue Donut Carb Cap by Empire Glassworks is made for the Puffco Peak Pro Rig and is constructed from high-quality, heat-resistant borosilicate glass. The accessory is shaped just like a Blue Donut with colored sprinkles and is full of worked glass details that make this tasty piece stand out!

The cap creates a great seal and features oculus-style directional air flow for a more controlled dabbing experience. Place the cap over your heated and loaded nail to prevent the vapor from escaping. Rotate the cap and direct the airflow while you inhale to vaporize all your content. The cap also helps to retain the heat so you can dab at a lower temperature for longer. 

The makers of the cap, Empire Glassworks, are based in Placentia, California – a short drive from Los Angeles. They put their emphasis on American-made glass that features exotic, exciting designs. Each piece they produce is unique thanks to their work with borosilicate glass. 

This donut-shaped accessory is easy to clean and makes a great spare or replacement part. Each piece comes out slightly different, so yours is guaranteed to be one of a kind! Order your Blue Donut Puffco Peak Pro Carb Cap by Empire Glassworks today for an unbeatable price!
